Lumen

Our 2015 vehicle, named Lumen (meaning light in Latin), competed in the 2015 Bridgestone World Challenge, placing 21st of 29 competitors in the Challenger class. In the Challenger class, efficiency is key as the car is unable to recharge from the grid during the race. Lumen is a highly efficient engineering design, utilising cutting edge solar panel, battery, and motor technologies, coupled with advanced materials and manufacturing techniques.
